Monster Houses may appear on floors 8-20. Shops may appear on floors 2-6. There is a chance of finding a buried item in floor 1 of Magma Cavern Pit. Darkness shrouds all floors.

The visual theme of floors 1 to 7 is normal rock with magma leaking out, for floors 8 to 17 it is hot rock with more magma present, and on floors 18 to 23, the rock becomes blackened with heat, featuring more magma than any other dungeon in the game. After floor 23 lies a Kangaskhan Rock and a door that leads to Magma Cavern Pit.

In Pokémon Mystery Dungeon: Rescue Team DX, the boss floor is made of solid rock floating above a layer of magma. When the boss battle starts, the ground shakes, causing the team's Pokémon to be scattered across the floor. Every few turns, magma floods the floor tiles or drains into the ground. Any non-Fire-type Pokémon that touches the magma will get burned.

The music in the regular Magma Cavern is unique to this dungeon, and is present on all floors (with the exception of floors 80-89 of Wish Cave).

In the Pokémon Mystery Dungeon: Ginji's Rescue Team manga

Magma Cavern was the location where Ginji and Mudkip headed in order to meet Ninetales and find out if Ginji was truly the cursed human causing natural disasters. They finally reached the Magma Cavern in Why I Became a Pokémon. The Answer Finally Revealed!!, but were surprised by the arrival of Team A.C.T., who had arrived to take Mudkip away. Refusing to be taken away, Ginji and Mudkip engaged in a battle against the Gold Rank team, but soon Ninetales arrived, halting the fight. Ninetales then revealed that the real cursed human being was actually Gengar, whose appearance in the Pokémon world was resulting in Groudon's awakening, thus causing all the natural disasters that had happened recently.

In Tears and Emotions - It's the Final Chapter!, Groudon was completely awakened. Gengar revealed that he intended to have Groudon destroy the entire Pokémon world, as it was the cause of his current state. Groudon, however, didn't listen to him, and almost crushed him under falling rocks, only to be saved by Mudkip. All of Ginji's friends from the Pokémon Square, as well as the Absol he and Mudkip had met at the Frosty Forest, arrived to their help. Thanks to Gengar, who had finally realized the error of his ways, distracting Groudon with his Double-Edge, everybody got a chance to attack Groudon together, successfully defeating the Continent Pokémon and saving the Pokémon world.
